Converting Time from 12-Hour to 24-Hour Format

When it comes to timekeeping, there are two main formats used worldwide - the 12-hour clock and the 24-hour clock. The 12-hour clock is widely used in everyday life, but many industries and professionals rely on the 24-hour clock for their operations. In this article, we will explore how to convert time from a 12-hour format to a 24-hour format.

Understanding the 24-Hour Clock

The 24-hour clock is a system that divides the day into 24 equal periods, each lasting one hour. It runs from midnight (00:00) to midnight (23:59). This format is used by most countries and is commonly used in business, medicine, transportation, and other professional settings.

Converting Time with Python

To convert time from a 12-hour format to a 24-hour format using Python, we can use the following algorithm:

* Check the last two elements of the input time (hours and minutes)

* If the hour is less than 12, add 0 to it

* If the meridiem is AM, do not modify the time

* If the meridiem is PM and the hour is less than 12, add 12 to the hour

* Convert the resulting time to a 24-hour format

Here's an example code snippet that demonstrates this conversion:

```

def convert(time):

hours, minutes = map(int, time.split(':'))

if string == 'AM' and hours == 12:

return f'{hours}:{minutes:02d}'

elif string == 'PM' and hours != 12:

return f'{hours + 12}:{minutes:02d}'

else:

return f'{hours}:{minutes:02d}'

print('24-hour Format time ::', convert('4:30 PM'))

```

This code takes a 12-hour time string as input, converts it to a 24-hour format, and returns the result. For example, if you input '4:30 PM', the output would be '16:30'.

Converting time from a 12-hour format to a 24-hour format is a simple process that can be achieved using Python programming language. By following the algorithm outlined above and using Python's built-in string manipulation functions, you can easily convert times in either direction. Whether you're working with schedules, appointments, or other time-sensitive information, knowing how to convert between these two formats can save you time and improve your productivity.
